WHM scripts. Where are?

hello everybody.
May be you can answer my question: Where are located WHM scripts? For example: when I want to show services status I see that the browser runs http://mydomain:2086/scripts/servup script. But this script is not in the /scripts directory on my server. And many others scripts I can't find on my server though the browser show me them.
Who can explain me this "Miracle"?
Thanks.
